(PhysOrg.com) -- A species of small, transparent roundworms have a highly evolved language in which they combine chemical fragments to create precise molecular messages that control social behavior, reports a new study from ...

In an emergency such as a factory fire, ascertaining which gases are present in the air is critical to preventing or minimizing poisoning (Fig. 1). This requires gas sensors that react quickly and provide a visual signal. ...

When nerve cells communicate with one another, specialized receptor molecules on their surfaces play a central role in relaying signals between them. A collaborative venture involving teams of chemists based at Ludwig-Maximilians-Universitat ...

For years, science has generally considered the phosphorylation of proteins -- the insertion of a phosphorous group into a protein that turns it on or off -- as perhaps the factor regulating a range of cellular processes ...

Scientists studying longevity thought it might be good to lack a copy of a gene, called IGF1 receptor, that is important in insulin signaling. Previous studies showed invertebrates that lacked the copy lived longer, even ...

For more than a century, the use of X-rays has been a prime diagnostic tool when it comes to human health. As it turns out, X-rays also are a crucial component for studying and understanding molecules, and a new approach ...

Upconversion emission materials are ideal for bioimaging due to its effectiveness as contrast agents for the detection of cancer cells, more so when the background emission of non-cancerous tissues can be minimised. These ...

Researchers from Hull, Bristol and Frankfurt have shown that a new technique for identifying molecular structure can be used effectively on small samples of biological proteins, particularly proteins that are targeted for ...
